The first flight of SpaceX’s Dragon capsule

SpaceX released a video Thursday showing a propulsive hover test of a prototype of the company’s Dragon crew capsule conducted two months ago, a milestone in the development of the spaceship’s rocket packs that will eventually guide the craft to helicopter-like landings.

SpaceX completed its third attempt to launch the Starlink 6-44 mission Friday night. Liftoff 8:21 p.m. ET (0021 UTC).

SpaceX’s Falcon 9 rocket is set for liftoff from Cape Canaveral early Thursday, heading due east over the Atlantic Ocean to deliver the Inmarsat 5 F4 communications satellite into orbit 32 minutes later.
